Thymic epithelial tumors (TETs) consist of a series of neoplasm that differ morphologically and biologically. Due to its rarity and indolent natural history, large-scale prospective trials have been lacking. This study aimed to evaluate long-term clinical outcomes and clinicopathologic features for TET after surgical resection and adjuvant treatments. ⋯ Pleura was the most common recurrence site (15 patients, 53.6%), and significantly associated with pleural recurrence-free survival. In conclusion, pleural involvement at diagnosis was the important prognostic factor, in addition to WHO histology and Masaoka stage. To prevent pleural recurrence and prolong survival, innovative therapeutic approaches warrant further investigations.
